[Elecraft] K3 comatose

[Stewart Rolfe]

Forgot I still had a telnet session open while doing a 1.68 to 1.69 MCU 
firmware upload; the upload failed and everything stopped responding, no 
communication between the K3 upload facility etc. The power button did 
nothing so eventually had to turn off the power supply; turning back on 
and then doing a 'Parameter Initialization' (page 55 ) powered up the 
radio but it is stuck in 'MCU LD'. In the words of Monty Python - "This 
is a dead K3"

I'm sure it's just in a coma and wonder if anyone here knows how to 
resuscitate prior to Aptos waking up; maybe I should play some music to 
it, always thought the K3 would be a Frank Zappa sort of radio..... 
There must be contingency plans for repairing wiped out firmware such as 
would happen if a power cut occurred mid way through a re-flash so I'm 
not panicking (yet).

This is always assuming the problem was caused by a serial port 
contention of some sort.......I'd closed the ports in Logger32 but still 
had the telnet open though not that sure why that would interrupt the PC 
to K3 comms.....
